Are {4cos^2(x),cos(2x),5} linearly independent? prove without wronskian

Expert Solution

not linearly independent.

As, 4Cos²x = 4(1+cos2x) = 4(cos2x)+5(4/5)

Since, one element is written as linear combination of other two, given set is not linearly independent.

Prove the follwing statements Suppose that S is a linearly independent set of vectors in the vector space V and let w be a vector of V that is not in S. Then the set obtained from S by adding w to S is linearly independent in V. If U is a subspace of a vector space V and dim(U)=dim(V), then U=V.
